Just because you’re driving an economy car or a (*gasp*) mini-van doesn’t mean you can’t make your vehicle sound like a souped up race car. Just plug the SoundRacer Street Racing Engine Simulator into your cigarette lighter and it automatically detects the RPMs of your car (by detecting voltage increases) and plays the appropriate sounds to make your car sound like powerful sports car. When you accelerate, decelerate, shift, rev the engine, whatever- it all makes the sounds change. Turn that Kia into a throaty V8 Shelby Mustang (soundwise anyway).
